Across
- 3. is the top of the wave. Highest point, particles are closest together
- 4. the vertical distance from crest to trough of a wave
- 5. is the distance between wave crests or troughs in a transverse wave
- 7. refers to how much waves bounce off of objects and change their direction of travel
- 10. a measure of how many wave crests or troughs pass a given point in a unit of time
- 13. the range of frequencies
- 14. the high or low quality of sound
- 15. a decrease of the density of something
- 16. waves of energy that travel through the Earth's layers
- 18. change in the frequency of a wave as the observer and source move toward or any from each other
- 20. the process of becoming smaller or being pressed together
- 21. the change in direction of a wave
- 22. the ability of an object or material to resume it's normal shape after being squished or compressed
- 23. a type of wave that vibrate at right angles to the direction of wave travel
Down
- 1. waves that travel parallel
- 2. process by which light changes passing through a narrow slit
- 6. a wave that is trapped on the surface of the Earth
- 8. is the bottom of a wave, lowest point of a transverse wave
- 9. the height of the wave from its trough or crest to its midpoint, is a measure of the wave's intensity
- 11. matter moves up and down as the wave travels through it, such as a wave you might make by moving in the water
- 12. a unit used to measure the intensity of sound
- 17. a disturbance that transfers energy from one point to another
- 19. waves that travel parallel to the direction of energy transport
